<p>The name of the DB parameter group to apply to the DB instance. Changing this setting doesn't result in an outage.

<p>The weekly time range (in UTC) during which system maintenance can occur, which might result in an outage. Changing this parameter doesn't result in an outage, except in the following situation, and the change is asynchronously applied as soon as possible. If there are pending actions that cause a reboot, and the maintenance window is changed to include the current time, then changing this parameter will cause a reboot of the DB instance. If moving this window to the current time, there must be at least 30 minutes between the current time and end of the window to ensure pending changes are applied.</p> <p>Default: Uses existing setting</p> <p>Format: ddd:hh24:mi-ddd:hh24:mi</p> <p>Valid Days: Mon | Tue | Wed | Thu | Fri | Sat | Sun</p> <p>Constraints: Must be at least 30 minutes</p>

Specifies if the DB instance is a Multi-AZ deployment. Changing this parameter doesn't result in an outage and the change is applied during the next maintenance window unless the <code>ApplyImmediately</code> parameter is set to <code>true</code> for this request.

The version number of the database engine to upgrade to. Currently, setting this parameter has no effect. To upgrade your database engine to the most recent release, use the <a>ApplyPendingMaintenanceAction</a> API.

Indicates that major version upgrades are allowed. Changing this parameter doesn't result in an outage and the change is asynchronously applied as soon as possible.

Indicates that minor version upgrades are applied automatically to the DB instance during the maintenance window. Changing this parameter doesn't result in an outage except in the following case and the change is asynchronously applied as soon as possible. An outage will result if this parameter is set to <code>true</code> during the maintenance window, and a newer minor version is available, and Neptune has enabled auto patching for that engine version.

<p> The new DB instance identifier for the DB instance when renaming a DB instance. When you change the DB instance identifier, an instance reboot will occur immediately if you set <code>Apply Immediately</code> to true, or will occur during the next maintenance window if <code>Apply Immediately</code> to false.
